(Update: A line has been added to this story to give insight into the motivation to investigate the parents' background)

CLEVELAND, Ohio -- Tamir Rice's father has a history of violence against women.

Leonard Warner, who fathered the 12-year-old boy fatally shot by a Cleveland police officer Saturday, has multiple convictions for the abuse of women, court records show.

People from across the region have been asking whether Rice grew up around violence. The Northeast Ohio Media Group investigated the backgrounds of the parents and found the mother and father both have violent pasts.

On Tuesday, Warner, 34, requested a continuance in his latest domestic violence case now moving through Cuyahoga County Common Pleas Court.

He is accused of punching his live-in girlfriend in the head and arms during an incident in August, according to a police record.

The victim's name is redacted.

Warner is estranged from Rice's mother Samaria Rice, who pleaded guilty to drug trafficking last year and assault in 2001.

The same year, on Dec. 8, 2001, she was the victim of domestic violence. Warner was her knife-wielding attacker at a home in the 3800 block of East 92nd Street, according to a court document. The report does not say if Rice was injured.

Warner was convicted in the case and sentenced to one year of probation, records show. The court noted that Warner had a prior domestic violence conviction in Euclid Municipal Court.

In 2010, Warner was arrested again for domestic violence. He pleaded guilty and was sentenced to two years probation.

Samaria Rice was the victim in that case, according to the court.

Even though their relationship ended, Samaria Rice again found herself the victim of violence at the hands of men.

She called Strongsville police twice in 2010 to report abuse from a boyfriend when she lived in that city.

In one case, told police that her live-in boyfriend, Michael Wiley, of Cleveland, had beaten her for two days.

Wiley was convicted of domestic violence and given a suspended 90-day jail sentence, county court records show.

Details about Warner's conviction in Euclid Municipal Court were not immediately available.
